Example Embodiment

[0017] See figure 1 with figure 2 The present invention includes a support base 2 composed of channel steel connected with the sludge conveying hole on the side wall of the sludge incinerator 1. The motor 4 placed on the support base 2 is connected to a rotating shaft 7 through a reducer, and a spiral blade 8 is provided on the rotating shaft 7. A sealed outer cylinder 5 with a circular or rectangular cross-section is provided on the periphery of the rotating shaft 7, and a square or circular material inlet 6 is provided on the upper part of one end of the outer cylinder 5. The support base 2 is fixed to the side wall of the sludge incinerator 1 by an inclined bracket 3, and the bracket 3 is made of channel steel. Two rotating shafts 7 are used and placed in parallel. After the motor 4 passes through the reducer, the coupling drives the two rotating shafts 7 to rotate toward each other. The ends of the two rotating shafts 7 are respectively provided with a cross-shaped break...

Abstract

The invention discloses a spiral conveyer for sludge incineration, and relates to the technical field of environment protection. The spiral conveyer comprises a supporting base connected with a sludge conveying hole in the side wall of a sludge incinerator. A motor arranged on the supporting base is connected with rotating shafts through a speed reducer, spiral blades are arranged on the rotating shafts, a sealed outer cylinder is arranged on the peripheries of the rotating shafts, and a material feeding opening is formed in the upper portion of one end of the outer cylinder. The supporting base is fixed to the side wall of the sludge incinerator through a support. The two rotating shafts are arranged in parallel, the motor drives the two rotating shafts to oppositely rotate firstly through the speed reducer and then through a shaft coupler, and the tail ends of the two rotating shafts are provided with cross-shaped material breakers respectively. A protecting box is arranged at the position where the conveyer is connected with the side wall of the sludge incinerator, a soft-connection expansion joint is arranged at the position where the material feeding opening is connected with a prior-stage conveying pipe, and a cooling air connector and an inspection hole are respectively formed in the upper portion of the outer cylinder. The spiral conveyer has the functions of breaking, stirring, loosening and conveying at the same time, is convenient to overhaul and can work in a long-time and continuously-efficient mode.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a screw conveyor used for sludge transportation in sewage treatment plant sludge incineration. Background technique [0002] In the sewage treatment plant, a large amount of sludge will be produced. The sludge has a high water content (generally about 75-85%), a small specific gravity, a colloidal liquid state, and a high organic content, which is easy to rot and smell. Sludge incineration be widely applied. In the process of sludge incineration, the transportation of sludge is very important. In the prior art, the sludge conveyors all adopt single-shaft operation, which has the problems of easy clogging, uneven sludge, and small conveying volume, and the sealed cylinder is inconvenient to repair, which seriously affects the normal conveying operation. Contents of the invention [0003] In order to solve the above-mentioned deficiencies in the prior art, the...
